Yes that what he meant by arenas. Will work in a similar fashion as RvR scenarios in Warhammer with even sides and controlled enviroment. They just havent been activated yet and been on the back burner for a while since the devs put in the game.
Um No.
Character copy is a function that will allow players to use their characters as they are from production shards on a Test Shard. The purpose is to allow players to test with their accounts as they would normally play on their own shards, with avatars they are familiar with.
Arenas is set to be PvP or Team v. Team.
Arenas was postponed due to High Seas launching and prep for publish 69 at the end of December.
It is now back on internal testing.
